The fourth and fifth Soil Moisture Active Passive Experiments (SMAPEx-4 and -5) were conducted at the beginning of the SMAP operational phase, May and September 2015, to: 1) evaluate the SMAP microwave observations and derived soil moisture (SM) products and 2) intercompare with the Soil Moisture and Ocean Salinity (SMOS) and Aquarius missions over...The use of soil moisture (SM) measurements from satellites has grown in recent years, fostering the development of new products at high resolution.

However, agricultural applications (irrigation, crop monitoring) and some hydrological applications (floods and modeling of small basins) require higher resolution SM information.

Nevertheless, different approaches can be used to circumvent the direct comparison. The 1 km resolution airborne data collected during the thr...AMSR-E sensitivity to soil moisture and its accuracy have been studied over a wide variety of surface conditions and weather regimes using both in situ measured data and aircraft derived soil moisture estimates.
The impact of the reflected Sun on radiometric measurements over a grass field and over an agricultural area reached 25 K and 17 K respectively. We propose to estimate the timing and the amount of irrigation throughout the agricultural season using optical and thermal Landsat-7/8 data. Period...The temporal frequency of the thermal data provided by current spaceborne high-resolution imagery systems is inadequate for agricultural applications. Two methods (FAO-Penman-Monteith (FAO-PM) and Hargreaves-Samani (HARG)) of the calculation of ET0 were tested in order to examine their impact on the established relationships. other remote sensing products over an small experimental watershed in Accurate estimates of ET at field scale are therefore critical. In this context, remote 2.By means of statisti...The FAO-56 dual crop coefficient (FAO-2Kc) model has been extensively used at the field scale to estimate the crop water requirements by means of the simulated evapotranspiration (ET) and its two components evaporation (E) and transpiration (T).
